The full text of Amir Saeed Iravani’s letter to UN Secretary-General António Guterres and UN Security Council President Michael Imran Kanu is below.
At the direction of the Administration, I write this letter to draw the attention of you and the members of the Security Council to extremely disturbing statements by the President of the United States that pose a serious threat to international peace and security and represent a serious violation of the United States’ obligations under international law. On October 29, 2025, the President of the United States announced on social media that he had directed the U.S. Department of the Army to “begin testing nuclear weapons on an equal basis” with other nuclear-weapon states, declaring that “the process will begin immediately.” Then, on October 31, 2025, in an interview with CBS’s 60 Minutes, he stated that the United States has “enough nuclear weapons to blow up the world 150 times.”
These reckless statements and nuclear rhetoric by the leaders of nuclear-weapon states constitute a clear threat to use nuclear weapons and a clear declaration of intent to resume nuclear testing. These are clear violations of the United States’ legally binding obligation under Article 6 of the Treaty on the Non-Proliferation of Nuclear Weapons (NPT) to pursue effective steps toward nuclear disarmament, and are in direct contradiction to the aims and objectives of the Comprehensive Nuclear-Test Ban Treaty (CTBT), to which the United States is a signatory, and its commitment to a moratorium on nuclear testing. Furthermore, these statements are especially egregious given that the United States is one of the three depositary governments of the NPT and therefore has special legal and moral responsibilities to uphold and preserve the integrity of the treaty. Far from fulfilling his responsibilities, the US president has openly glorified nuclear weapons and engaged in rhetoric threatening catastrophic destruction. This dangerously undermines decades of joint international efforts towards nuclear disarmament and non-proliferation, risks igniting a new nuclear arms race, and dangerously lowers the threshold for nuclear confrontation.
Equally alarming, this comes at a time when the United States is deliberately spreading falsehoods and disinformation to mislead the international community, falsely portraying Iran’s entirely peaceful nuclear program as a threat to international peace and security. The unlawful act of aggression committed by the United States on June 24, 2025, through a deliberate airstrike on peaceful, IAEA-protected nuclear facilities in Iran, a non-nuclear-weapon state in the NPT, is a flagrant violation of international law, the Charter of the United Nations, and a grave attack on the very foundations of the global nuclear disarmament and non-proliferation regime.
Given the gravity of this situation, the Islamic Republic of Iran respectfully requests the Secretary-General, acting under Article 99 of the Charter of the United Nations, to urgently submit this matter to the Security Council to assess its impact on the global nuclear disarmament and non-proliferation regime. Iran further urges the Security Council to address these alarming developments in order to fulfill its primary responsibility of maintaining international peace and security.
I would appreciate it if you would circulate this letter as an official Security Council document.
